๐Ÿ“š Quick Study Guide

  • ๐ŸŽ A system of equations is a set of two or more equations containing two or more variables.
  • ๐Ÿ”ข The solution to a system of equations is the set of values that satisfy all equations in the system simultaneously.
  • ๐Ÿ“ˆ Graphing: Graph each equation and find the point(s) of intersection. This method is best for simple equations.
  • โž• Substitution: Solve one equation for one variable and substitute that expression into the other equation.
  • โž– Elimination: Add or subtract the equations to eliminate one variable. Sometimes you need to multiply one or both equations by a constant first.
  • ๐Ÿ’ก When solving, if you get a true statement (e.g., $0 = 0$), the system has infinitely many solutions. If you get a false statement (e.g., $0 = 1$), the system has no solution.
  • โœ๏ธ Remember to check your solution by plugging the values back into the original equations!
